Abstract

The invention relates to an electric energy meter that comprises a sampling board, a main control board and a thermostatic bath, wherein the sampling board is used for sampling input voltage and inputcurrent, converting the sampled input voltage and input current from an analog signal into a digital signal and providing the digital signal to the main control board; the main control board is usedfor analyzing according to the digital signal; wherein the sampling plate comprises an analog signal processing module, the analog signal processing module is used for processing an analog signal input into the sampling plate, and the thermostatic bath is arranged at the periphery of the analog signal processing module of the sampling plate and is used for heating the working environment temperature of the analog signal processing module to a preset temperature. By means of the mode, the electric energy meter of the invention can adapt to calibration reference conditions of different temperatures, humidity and the like and can stably work in different temperature and humidity environments.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to an electric energy meter. Background technique [0002] As a smart energy meter, which is composed of a measurement unit, a data processing unit, and a communication unit, it has the functions of electric energy measurement, information storage and processing, real-time monitoring, automatic control, and information interaction. As the end of the power grid, its accuracy , Reliability is closely related to the interests of thousands of households. [0003] At present, the technical requirements for electric energy meters and large-scale automatic verification devices still follow the technical requirements of mechanical electric energy meters and traditional verification devices, and the reference conditions for verification still use traditional laboratory verification conditions. At present, it is necessary to use high-cost precision air conditioners to realize the control...
